Who the hell looks at a 600-foot cliff in South Africa and says "let's build a rope swing here"? Mike Wilson and Andrew Kirkpatrick, that's who. Luckily, they filmed the madness as they sent a bunch of their friends flying on the world's biggest, scariest, craziest rope swing.

This thing is so big, they needed a damned pickup truck to hoist the jumpers back up to the top. I watch a lot of crazy videos, but this is the first one that actually gave me vertigo. Wild.
